Topic: Correlative Characterization and Multiscale Understanding of Dynamic Microstructure Evolution in Materials

Advanced structural and functional materials undergo complex, dynamic microstructural changes during processing, deformation, thermal exposure, and phase transformations. Understanding these dynamic microstructural evolution mechanisms at multiple length and time scales is essential for tailoring material properties and designing next-generation advanced alloys and functional devices.

Recent breakthroughs in advanced in situ characterization techniques—such as in situ electron microscopy (TEM/SEM), in situ nanoindentation, synchrotron X-ray diffraction, neutron scattering, accelerator-based facilities, electron backscatter diffraction (EBSD), atom probe tomography (APT), and Digital Image Correlation (DIC)—combined with multiscale modeling approaches, have provided unprecedented insights into real-time microstructural phenomena. These phenomena include dislocation dynamics, deformation twinning, phase transformations, recrystallization, dynamic recovery, and defect evolution.

This Special Issue aims to bring together cutting-edge research and review articles focusing on the latest advancements in in situ characterization and multiscale analysis of dynamic microstructural behavior. We welcome high-quality contributions covering advanced structural metals, high-entropy alloys, functional materials, semiconductor defects, and additive manufacturing.
